Seems like heater control valves are a hot/cool problem. I have a 1997 740i, and the
heat is slowley going away. So, my control valve must be stuck closed/ shut or some
other malfunction. I think I could fix the sucker if I could find its location. Where is
the location of this valve on the 1997 740i ??. Thanks for your help.
